How to Fix CVE-2024-21541

To remediate this vulnerability, upgrade all affected Dom iterator dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

dom-iterator fixed: 1.0.1 
npm install dom-iterator@1.0.1
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

npm ls dom-iterator

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2024-21541, inspect your project dependencies using npm:

npm ls dom-iterator

Analyze the terminal output to locate any version of Dom iterator in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.0.1), your application is affected.

Note: The npm ls dom-iterator command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-94: Improper Control of Generation of Code ('Code Injection'), where the product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. In Dom iterator, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

Versions of the package dom-iterator before 1.0.1 are vulnerable to Arbitrary Code Execution due to use of the Function constructor without complete input sanitization. Function generates a new function body and thus care must be given to ensure that the inputs to Function are not attacker-controlled. The risks involved are similar to that of allowing attacker-controlled input to reach eval.
